Data on vessel wall thickness measurements of intracranial arteries derived from human circle of Willis specimens

Data in Brief, 2018
In this article, we report data on vessel wall thickness parameters derived from different arterial segments of the circle of Willis and its primary branches in patients with and without cerebrovascular disease.

Clade‐wide morphological and functional variation of the sauropsid columella

The Anatomical Record, EarlyView.
Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.

Exploring student perceptions of integrating mixed reality with cadaveric teaching in undergraduate neuroanatomy education: A qualitative study

Anatomical Sciences Education, EarlyView.
Abstract Mixed reality (MR) using head‐mounted displays provides three‐dimensional visualizations that have been suggested to enhance learning when used alongside conventional anatomy teaching in medical education. This study explored student perceptions of the integration of MR and traditional cadaveric learning, and their optimal delivery to support ...

Cerebral Artery Diameter in Inbred Mice Varies as a Function of Strain

Frontiers in Neuroanatomy, 2018
Many strains of mice are utilized in mouse models of cerebrovascular diseases. Variations in vascular anatomy between these strains has been documented and may influence the phenotype in stroke models.

SO2 Transfer Enabled by an Easy‐to‐Handle Ionic Liquid

Chemistry – A European Journal, EarlyView.
Best of both worlds: The ionic liquid [NEt3Me][Cl(SO2)n] unites the atom economy and low cost of sulfur dioxide with the safety and applicability of common surrogates, streamlining SO2 transfer to access to 3‐sulfolenes, sulfonamides, and SuFEx reagents.

Morphometric analysis of Willis circle arteries

Archives of Pharmacy Practice, 2013
Introduction: Willis arterial circle (circulus arteriosus cerebri Willisi) is the most important part of the collateral circulatory system of the brain. It functions in normal and pathological situations such as valvular mechanism and thus allows optimal

Numerical simulation of the blood flow behavior in the circle of Willis [PDF]

BioImpacts, 2014
Introduction: This paper represents the numerical simulation of blood flow in the circle of Willis (CoW). Circle of Willis is responsible for the oxygenated blood distribution into the cerebral mass.

Chromatin Conformation Links Putative Enhancers in Intracranial Aneurysm–Associated Regions to Potential Candidate Genes

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019
Background We previously showed that intracranial aneurysm (IA)–associated single‐nucleotide polymorphisms are enriched in promoters and putative enhancers identified in the human circle of Willis, on which IAs develop, suggesting a role for promoters ...

Microsurgery for aneurysms on the circle of Willis.

South African medical journal = Suid-Afrikaanse tydskrif vir geneeskunde, 1974
A description of a microsurgical approach for aneurysms on the anterior part of the circle of Willis is given. Certain practical points are stressed. The operative results obtained in 37 consecutive aneurysms operated on in 30 patients are discussed.S. Afr. Med. J., 48, 825 (1974).
